MSS-P-2.5(40) Equivalent & Substitute Parts

Part Overview

The MSS-P-2.5(40) is a coaxial connector plug manufactured by Hirose Electric Co Ltd, designed for 50 Ohm RF applications with free hanging (in-line) solder termination. This connector operates at frequencies up to 1 GHz and is rated for 3000 mating cycles. The part is currently listed as obsolete, making identification of compatible substitute components essential for ongoing system maintenance and new design implementations where legacy compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MSS-P-2.5(40) is determined by strict adherence to the following electrical and mechanical parameters:

Critical Parameters for Substitution:

• Connector Style: MSS
• Connector Type: Plug, Male Pin
• Impedance: 50 Ohms
• Contact Termination: Solder
• Shield Termination: Crimp
• Mounting Type: Free Hanging (In-Line)
• Fastening Type: Snap-On
• Frequency - Max: 1 GHz
• Number of Ports: 1
• Mating Cycles: 3000
• Base Product Number: MSS-P
• RoHS Status: RoHS Compliant

Allowable Variations:

• Cable Group: Different cable group designations (2.5D-2V, 1.5D-2V) are permitted as they represent different cable diameter compatibility
• Operating Temperature Range: Extended ranges are acceptable
• Product Status: Active status substitutes are preferred for obsolete parts
• Packaging: Variations in packaging format (Bulk, Bag) do not affect electrical or mechanical compatibility

The identified substitute parts MSS-P-1.5-A(40) and MSS-P-1.5DV meet all critical parameters while differing only in cable group specification and operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

Both MSS-P-1.5-A(40) and MSS-P-1.5DV are active product alternatives to the obsolete MSS-P-2.5(40). Selection between these substitutes depends on application-specific requirements:

MSS-P-1.5-A(40) maintains identical operating temperature specifications (-30°C ~ 60°C) to the original part and is available in bulk packaging. This option provides direct thermal compatibility for applications operating within the original temperature envelope.

MSS-P-1.5DV extends the operating temperature range to -40°C ~ 85°C and includes a voltage rating specification of 150 V. This part is available in bag packaging and accommodates applications requiring broader environmental operating conditions.

Both substitutes are RoHS compliant and maintain all critical electrical and mechanical parameters. The primary design consideration is cable group compatibility: the original MSS-P-2.5(40) accommodates 2.5D-2V cable, while both substitutes accommodate 1.5D-2V cable. Cable group selection must align with the specific cable diameter used in the application.

Frequently Asked Questions (FAQ)

Q: Can MSS-P-1.5-A(40) and MSS-P-1.5DV be used interchangeably with MSS-P-2.5(40)?

A: Both parts meet all critical electrical and mechanical substitution parameters. However, cable group compatibility must be verified. The original part supports 2.5D-2V cable, while substitutes support 1.5D-2V cable. Connector selection must match the cable diameter specified in the application.

Q: What is the significance of the cable group designation in the part number?

A: Cable group designation (2.5D-2V vs. 1.5D-2V) indicates the compatible cable diameter range. This is a mechanical compatibility parameter that must align with the cable used in the application. Mismatched cable groups will result in improper mating.

Q: Are there temperature limitations when substituting MSS-P-1.5-A(40) for MSS-P-2.5(40)?

A: MSS-P-1.5-A(40) maintains the same operating temperature range (-30°C ~ 60°C) as the original part. Applications operating within this range experience no thermal limitations. For applications requiring extended temperature operation, MSS-P-1.5DV (-40°C ~ 85°C) is the appropriate selection.

Q: Does the voltage rating specification on MSS-P-1.5DV affect substitution decisions?

A: The voltage rating of 150 V on MSS-P-1.5DV is an additional specification not listed for the original part. This specification does not prevent substitution; it indicates the part is rated for this voltage level. Applications operating below 150 V experience no compatibility issues.

Q: How do packaging differences (Bulk vs. Bag) affect part selection?

A: Packaging format does not affect electrical or mechanical compatibility. Selection between bulk and bag packaging is determined by procurement and inventory management requirements only.

Q: Is RoHS compliance maintained across all substitute options?

A: All parts listed—MSS-P-2.5(40), MSS-P-1.5-A(40), and MSS-P-1.5DV—are RoHS compliant. Regulatory compliance is maintained across all substitution options.
