Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PS-40SM-D4P1-1C are identified based on the following critical parameters that determine functional equivalence:

• Connector Type & Contact Configuration: Receptacle with female socket contacts
• Position Count & Pitch: 40 positions at 0.100" (2.54mm) pitch
• Row Configuration: 2 rows with 0.100" (2.54mm) row spacing
• Termination Method: IDC cable termination capability
• Contact Finish: Gold plating for corrosion resistance and electrical performance
• Mounting Style: Free hanging in-line configuration
• Environmental Compliance: RoHS compliance and MSL rating

The CWR-217-40-0000 from CW Industries meets these core substitution criteria. Both parts share identical position count, pitch, row configuration, and IDC termination methodology. Both maintain gold contact finish and RoHS compliance status, ensuring electrical and mechanical compatibility in equivalent applications.

Parameter Comparison

Engineering Selection Recommendations

Both the PS-40SM-D4P1-1C and CWR-217-40-0000 are active production parts with full RoHS compliance and unlimited moisture sensitivity ratings. Selection between these parts should be based on:

PS-40SM-D4P1-1C (JAE Electronics): Select when the original design specification requires JAE Electronics sourcing or when the specific contact finish thickness of 3.94µin (0.10µm) is required. This part supports both discrete and ribbon cable wire types.

CWR-217-40-0000 (CW Industries): Select as an alternative when CW Industries sourcing is preferred or when higher contact finish thickness of 10.0µin (0.25µm) is beneficial for extended contact life. This part includes strain relief features and is optimized for ribbon cable applications. ROHS3 compliance provides extended regulatory coverage.

Both parts maintain identical electrical and mechanical interfaces, ensuring direct substitution capability in applications where connector sourcing flexibility is permitted.

Frequently Asked Questions (FAQ)

Q: Can CWR-217-40-0000 directly replace PS-40SM-D4P1-1C in existing designs?

A: Yes. Both connectors share identical position count (40), pitch (0.100"), row configuration (2 rows at 0.100" spacing), and IDC termination method. The mechanical and electrical interfaces are equivalent, permitting direct substitution.

Q: What is the difference in contact finish thickness between these parts?

A: The PS-40SM-D4P1-1C has a contact finish thickness of 3.94µin (0.10µm), while the CWR-217-40-0000 has 10.0µin (0.25µm). The thicker finish on the CW Industries part provides increased contact durability and may extend service life in high-cycle mating applications.

Q: Are both parts RoHS compliant?

A: Yes. The PS-40SM-D4P1-1C is RoHS Compliant, and the CWR-217-40-0000 is ROHS3 Compliant. Both meet RoHS requirements for lead-free construction.

Q: What wire gauges are supported?

A: The PS-40SM-D4P1-1C supports 28 AWG wire. The CWR-217-40-0000 does not specify a wire gauge limitation in the provided data, indicating broader wire gauge compatibility for ribbon cable applications.

Q: What is the difference in fastening type?

A: The PS-40SM-D4P1-1C uses a latch holder fastening mechanism. The CWR-217-40-0000 does not specify a fastening type but includes strain relief features for cable protection.

Q: Are both parts available in inventory?

A: Yes. The PS-40SM-D4P1-1C has 912 units in stock, and the CWR-217-40-0000 has 1254 units in stock, both listed as new original inventory.
