Substitute Part Grouping Explanation

The PC142AX is a direct substitute for the PC142A within the TINI-D-JAX® series. Substitution is valid based on the following criteria:

Matching Parameters:

• Identical connector type (Phone Jack, Female, Mono)
• Identical mating diameter (4.65mm / 0.14")
• Identical contact configuration (3 Contacts, 2 Conductors)
• Identical mounting type (Through Hole)
• Identical termination method (Solder Eyelet)
• Identical electrical ratings (48VDC, 250 mA)
• Identical material specifications (Copper Alloy contacts, Plastic housing)
• Identical compliance certifications (ROHS3 Compliant)

Difference:

• Packaging: PC142A supplied in standard packaging; PC142AX supplied in bulk packaging

Both parts are manufactured by Switchcraft Inc. and maintain full electrical and mechanical compatibility for PCB applications.

Parameter Comparison

Engineering Selection Recommendations

Both PC142A and PC142AX are active production parts manufactured by Switchcraft Inc. and maintain full ROHS3 compliance. Selection between these parts should be based on packaging and procurement requirements:

• PC142A: Select when standard packaging is required or for lower-volume applications.
• PC142AX: Select for bulk procurement applications or when higher inventory availability is needed.

Both parts are electrically and mechanically identical and will function identically in PCB applications requiring 4.65mm mono phone jack connectors with through-hole solder eyelet termination.

Frequently Asked Questions (FAQ)

Q: Can PC142AX be used as a direct replacement for PC142A? A: Yes. PC142AX is a direct substitute for PC142A. Both parts are identical in electrical specifications, mechanical dimensions, contact configuration, and material composition. The only difference is packaging format.

Q: What is the mating diameter tolerance for these connectors? A: The industry-recognized mating diameter is 4.65mm (0.14"). The actual measured diameter is 0.145" (3.68mm). This specification applies to both PC142A and PC142AX.

Q: Are these connectors suitable for high-frequency applications? A: These are unshielded mono phone jack connectors rated for 48VDC and 250 mA. Frequency specifications are not provided in the product parameters. Application suitability should be determined based on your specific circuit requirements.

Q: What is included with each connector? A: Each connector includes 3 pieces: 1 Connector, 1 Nut, and 1 Washer.

Q: Are these connectors RoHS compliant? A: Yes. Both PC142A and PC142AX are ROHS3 compliant.

Q: What is the difference between PC142A and PC142AX packaging? A: PC142A is supplied in standard packaging, while PC142AX is supplied in bulk packaging. This distinction affects procurement and handling but does not impact electrical or mechanical performance.
