Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: TE Connectivity 5745928-2

The 5745928-2 is the direct equivalent to the 745928-2 within the TE Connectivity AMPLIMITE HD-20 series. Both parts share identical mechanical and electrical specifications. The primary distinction is RoHS compliance status: the 5745928-2 is RoHS Compliant, whereas the original 745928-2 is RoHS non-compliant. Selection of the 5745928-2 is appropriate for applications requiring RoHS compliance or for new designs where regulatory requirements mandate lead-free materials. Inventory availability is higher for the 5745928-2 (1709 units versus 636 units).

Secondary Substitutes: Amphenol ICC D25S91C4GV00LF and D25S90C6GX00LF

Both Amphenol ICC Delta D series connectors provide functional equivalence to the 745928-2 with the following distinctions:

The D25S91C4GV00LF maintains the mating-side female screwlock flange feature identical to the original part. This connector features a tin-nickel plated steel shell, phosphor bronze contacts, and an extended operating temperature range of -55°C ~ 125°C. RoHS and REACH compliance are both confirmed.

The D25S90C6GX00LF features a housing/shell flange configuration and includes a board lock feature. This variant also provides tin-nickel plating, phosphor bronze contacts, and the extended temperature range. Contact finish thickness is specified at 30.0µin (0.76µm) with a current rating of 5A per contact and voltage rating of 300V.

Selection of Amphenol ICC substitutes is appropriate when cross-manufacturer standardization is required, when extended operating temperature performance is necessary, or when specific compliance certifications from alternative suppliers are mandated by procurement specifications.

Frequently Asked Questions (FAQ)

Q: Can the 5745928-2 be used as a direct replacement for the 745928-2?

A: Yes. The 5745928-2 is a direct equivalent within the same AMPLIMITE HD-20 series. All mechanical, electrical, and functional parameters are identical. The primary difference is RoHS compliance status. Both parts are pin-compatible and mechanically interchangeable.

Q: What are the key differences between TE Connectivity and Amphenol ICC substitutes?

A: The Amphenol ICC Delta D series connectors (D25S91C4GV00LF and D25S90C6GX00LF) differ in shell material finish (tin-nickel versus tin-plated), dielectric material (PBT versus polyamide), contact material (phosphor bronze versus copper alloy), and operating temperature range (-55°C ~ 125°C versus -55°C ~ 105°C). The D25S90C6GX00LF additionally features a housing/shell flange and board lock feature, whereas the D25S91C4GV00LF maintains the mating-side female screwlock configuration.

Q: Are all substitute parts RoHS compliant?

A: The 5745928-2, D25S91C4GV00LF, and D25S90C6GX00LF are all RoHS Compliant. The original 745928-2 is RoHS non-compliant. For applications requiring RoHS compliance, any of the three substitute parts are suitable.

Q: What is the difference between the D25S91C4GV00LF and D25S90C6GX00LF?

A: Both are Amphenol ICC Delta D series connectors with identical position count, shell size, and mounting type. The D25S91C4GV00LF features a mating-side female screwlock flange, matching the original 745928-2 configuration. The D25S90C6GX00LF features a housing/shell flange and includes a board lock feature. Contact finish thickness is specified for the D25S90C6GX00LF (30.0µin) and flash for the D25S91C4GV00LF.

Q: Can I mix and match connectors from different manufacturers in the same assembly?

A: All substitute parts maintain mechanical and electrical compatibility through matching shell size (3/DB/B), position count (25), and mounting type (through-hole press-fit). However, design consistency and procurement standardization typically favor using connectors from a single manufacturer within a single product line.

Q: What is the operating temperature difference between the original part and substitutes?

A: The 745928-2 and 5745928-2 operate from -55°C to 105°C. The Amphenol ICC substitutes (D25S91C4GV00LF and D25S90C6GX00LF) operate from -55°C to 125°C, providing an extended upper temperature limit of 20°C. Selection of extended-temperature variants is appropriate for applications with elevated thermal environments.

Q: Are there any flange feature differences I should consider?

A: Yes. The 745928-2, 5745928-2, and D25S91C4GV00LF all feature a mating-side female screwlock (4-40) flange. The D25S90C6GX00LF features a housing/shell flange (4-40) configuration. Flange selection depends on mounting surface geometry and mechanical retention requirements.

Q: What is the inventory status for each part?

A: The 5745928-2 has the highest inventory at 1709 units. The D25S91C4GV00LF has 1492 units, the 745928-2 has 636 units, and the D25S90C6GX00LF has 855 units. Inventory levels may influence part selection for immediate availability requirements.
