Application Context & Design Challenge
Financial terminals and office automation equipment—including money counters, cash registers, binding machines, and laminators—require connectors that balance three critical factors: reliable electrical contact for signal integrity, compact footprint for space-constrained PCB designs, and cost-effectiveness for high-volume production. In our application engineering work with POS system manufacturers and office equipment producers, we frequently encounter design teams evaluating alternative connector sources. One recurring challenge is finding a supplier that can match the original footprint while maintaining electrical and mechanical performance at a competitive price point.
SCONDAR Product Matching for Financial & Office Equipment
SCONDAR has validated several wire-to-board connector series that are footprint-compatible with common financial terminal and office equipment designs. These products cover the typical pitch ranges (1.0mm–2.54mm) and current ratings (1A–3A) required for signal transmission and low-power connections in these applications.
Technical Specification Overview

| Текущий рейтинг | 1A | 3A | 3A |
| Original Equivalent | PicoBlade | Hirose DF11 | KK 254 |
Design-In Considerations: Mechanical & Process
Pitch and PCB Footprint Compatibility
The SCT1251 series is designed as a direct footprint-compatible alternative to the PicoBlade 1.25mm pitch connector. When substituting this part, the key validation step is confirming that the PCB drill holes and solder pad layout align without modification. SCONDAR recommends performing a dimensional check using the product drawing before committing to production.
Crimping Process for Wire Termination
The SCT1251 and SCT2011 series use standard crimp-style terminals. For production environments that prioritize consistency, SCONDAR recommends using automated crimping equipment with pull-out force testing. Typical pull-out force for these series ranges from 20N to 30N when terminated with 28AWG–30AWG wire, depending on the specific wire construction.
Locking Mechanism Selection
For financial terminals and office equipment that experience minimal vibration during operation, friction lock designs (such as the SCT2541) provide reliable retention while simplifying the mating and unmating process during assembly and maintenance. If the application involves tabletop equipment that may be moved or repositioned, consider the SCT1251 with its two-point contact design for enhanced reliability.
Quality Assurance & Supply Chain
SCONDAR maintains ISO 9001:2015 certified quality management systems. All connector products undergo incoming quality control (IQC) inspection, in-process quality control (IPQC), and 100% electrical testing before shipment. Key quality verifications include contact resistance testing (typically <20mΩ) and insulation resistance verification (typically >100MΩ). Products are available in tray, reel, or tube packaging to support automated assembly processes. For high-volume financial equipment production, SCONDAR can supply connectors in pick-and-place compatible packaging with predictable lead times.
Frequently Asked Questions
Q: How do I verify PCB footprint compatibility without modifying my board layout?
A: SCONDAR provides detailed product drawings with full dimensional data including PCB layout patterns. Request the product specification sheet and verify the hole diameter, pad dimensions, and pin positions against your existing design. For critical applications, we recommend requesting sample units for a fit-check before volume procurement.
Q: What wire gauges are recommended for the SCT1251 series?
A: The SCT1251 series is designed for 28AWG–30AWG stranded or solid wire. The terminal contact design provides reliable electrical and mechanical connection within this range. If your application requires heavier gauge wire, consider the SCT2011 (up to 22AWG) or SCT2541 (up to 20AWG) series as alternatives.
