Key Parameters

Substitute Part Grouping Explanation

Substitution for the MS3112E16-26S is based on the following critical parameters that must remain constant:

• Connector Type & Position Count: Receptacle configuration with 26 positions ensures mechanical and electrical compatibility with mating plugs
• Shell Size: 16-26 insert size maintains physical fit within existing panel cutouts and connector housings
• Mounting Configuration: Panel mount with flange fastening preserves installation compatibility
• Termination Method: Solder cup termination allows direct PCB or harness integration without additional adapters
• Fastening Mechanism: Bayonet lock ensures secure mating with corresponding plug connectors
• Operating Temperature Range: -55°C ~ 125°C defines the thermal envelope for system operation
• Environmental Resistance: Environment resistant rating maintains performance in harsh conditions

The MSW02E16-26S from Milspecwest, LLC meets all these critical parameters and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The MSW02E16-26S is a qualified substitute for the MS3112E16-26S based on the following factors:

Mechanical Compatibility: Both connectors share identical shell size (16-26), mounting configuration (panel mount with flange), and fastening mechanism (bayonet lock), ensuring direct physical interchangeability.

Electrical Compatibility: Both connectors maintain the same 26-position receptacle configuration with female sockets and solder cup termination. The MSW02E16-26S provides specified current (7.5A) and voltage (800V) ratings, which establish a defined electrical envelope for the connector class.

Environmental Performance: Both connectors operate across the identical temperature range (-55°C ~ 125°C) and provide environment resistant ingress protection, meeting harsh environment requirements.

Compliance Status: Both connectors are RoHS non-compliant, maintaining consistency with legacy military and aerospace specifications. Both carry ECCN EAR99 classification.

Availability: The MSW02E16-26S is currently active in production with 1059 units in stock, providing immediate procurement availability compared to the discontinued MS3112E16-26S.

Frequently Asked Questions (FAQ)

Q: Can the MSW02E16-26S directly replace the MS3112E16-26S in existing assemblies?

A: Yes. Both connectors share identical shell size (16-26), mounting configuration (panel mount flange), termination method (solder cup), and fastening type (bayonet lock). The 26-position receptacle configuration ensures compatibility with existing mating plugs.

Q: What are the key differences between these two connectors?

A: The primary differences are manufacturer (Amphenol vs. Milspecwest), shell finish (Olive Drab Chromate over Cadmium vs. Cadmium), contact finish (Gold vs. Cadmium), and product status (discontinued vs. active). The MSW02E16-26S provides specified electrical ratings (7.5A, 800V) not listed for the original part.

Q: Are there any compatibility concerns with the different shell finishes?

A: Both finishes provide corrosion protection suitable for environment resistant applications. Shell finish differences do not affect mechanical fit or electrical performance. Selection should be based on system-level corrosion requirements and existing connector inventory.

Q: Does the MSW02E16-26S meet the same military specifications?

A: The MSW02E16-26S is designated as a 26482 Style Connector, aligning with MIL-DTL-26482 series specifications. Both connectors are RoHS non-compliant and carry EAR99 ECCN classification, consistent with military and aerospace requirements.

Q: What is the packaging difference between these connectors?

A: The MS3112E16-26S packaging is not specified in available data. The MSW02E16-26S is supplied in bag packaging. Packaging does not affect connector performance or interchangeability.
