D25S24A6GX00 D-Sub Receptacle Connector - Equivalent & Substitute Parts

Part Overview

The D25S24A6GX00 is a 25-position D-Sub receptacle connector manufactured by Amphenol ICC (FCI) in the Delta D series. This through-hole solder-terminated connector features female sockets with gold-plated phosphor bronze contacts and a tin-plated steel shell. The connector is actively produced and maintains 1075 pieces in current inventory stock.

D-Sub connectors of this specification are essential in legacy and industrial applications requiring standardized 25-position signal connectivity. Identifying equivalent substitute parts becomes necessary when managing supply chain continuity, addressing component obsolescence concerns, or optimizing procurement across manufacturing batches.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the D25S24A6GX00 is determined by strict equivalence across the following critical parameters:

• Connector type and gender (receptacle, female sockets)
• Position count (25 positions)
• Shell size and layout (3 / DB, B)
• Mounting method (through hole)
• Termination type (solder)
• Electrical ratings (5A current, 300V voltage)
• Operating temperature range (-55°C to 125°C)
• Contact material and finish specifications (phosphor bronze with gold plating)
• Dielectric material (PBT)
• Mechanical features (board lock, 4-40 flange)

The substitute part D25S24A6GX00LF maintains full electrical and mechanical compatibility with the main part across all these parameters. The primary difference lies in shell plating specification (tin-nickel versus tin) and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both D25S24A6GX00 and D25S24A6GX00LF are active production components from Amphenol ICC (FCI) with identical electrical and mechanical specifications. Selection between these parts should be based on regulatory and compliance requirements:

The D25S24A6GX00LF is the preferred selection for applications subject to RoHS directives or requiring RoHS compliance documentation. This part carries RoHS Compliant status and REACH Unaffected designation, making it suitable for European Union markets and regulated industries.

The D25S24A6GX00 remains appropriate for applications without RoHS compliance mandates or for legacy system maintenance where non-compliant components are already in use. This part maintains full electrical and mechanical compatibility.

The tin-nickel plating on the D25S24A6GX00LF provides enhanced corrosion resistance compared to the tin plating on the D25S24A6GX00, offering potential advantages in harsh environmental conditions or extended storage scenarios.

Frequently Asked Questions (FAQ)

Q: Are D25S24A6GX00 and D25S24A6GX00LF mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including shell size (3 / DB, B), mounting type (through hole), flange configuration (4-40), and board lock features. They mount identically on PCBs and mate with the same plug connectors.

Q: What is the difference between tin plating and tin-nickel plating on the shell?

A: Tin-nickel plating (D25S24A6GX00LF) provides superior corrosion resistance and environmental protection compared to tin plating (D25S24A6GX00). For applications in corrosive environments or with extended shelf life requirements, tin-nickel plating offers extended durability.

Q: Can I use D25S24A6GX00LF as a direct replacement for D25S24A6GX00?

A: Yes, for applications where RoHS compliance is required or preferred. The D25S24A6GX00LF is electrically and mechanically equivalent with the added benefit of RoHS compliance. No design changes are necessary.

Q: What does RoHS Compliant status mean for the D25S24A6GX00LF?

A: RoHS Compliant indicates the part meets Restriction of Hazardous Substances directives, containing no lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls, or polybrominated diphenyl ethers above specified thresholds. This is required for products sold in the European Union and many regulated markets.

Q: Are both parts suitable for the same temperature range?

A: Yes. Both D25S24A6GX00 and D25S24A6GX00LF operate across the identical temperature range of -55°C to 125°C with no derating required within this specification.

Q: What is the current rating per contact?

A: Both connectors are rated for 5A per contact. The D25S24A6GX00LF specification explicitly states "5A per Contact" while the D25S24A6GX00 specifies "5A" with the same electrical performance.

Q: Which part should I select for new designs?

A: For new designs, D25S24A6GX00LF is the recommended selection due to RoHS compliance, enhanced shell plating, and higher current inventory availability (1831 pcs versus 1075 pcs). Both parts are active production items with no obsolescence risk.
