Key Parameters

Substitute Part Grouping Explanation

The RAPC742X qualifies as a direct substitute based on identical electrical and mechanical parameters. Substitution compatibility is determined by the following critical parameters:

• Connector type (Jack) and gender (Male)
• Mating diameter specifications: 0.039" (1.00mm ID), 0.177" (4.50mm OD)
• Contact configuration: 2 Conductors, 3 Contacts with Single Switch, Normally Closed
• Mounting configuration: Through Hole, Right Angle orientation
• Termination method: Solder
• Current rating: 3 A
• Contact and housing materials: Copper Alloy contacts with Tin plating, Thermoplastic housing

The RAPC742X maintains full compatibility across all specified parameters, enabling direct substitution in applications requiring the RAPC742.

Parameter Comparison

Engineering Selection Recommendations

Both the RAPC742 and RAPC742X are active products manufactured by Switchcraft Inc. and maintain ROHS3 compliance. Selection between these parts should be based on packaging requirements and inventory availability. The RAPC742 is available in standard packaging with 1008 units in stock, while the RAPC742X is supplied in bulk packaging with 1697 units available. Both parts meet identical electrical and mechanical specifications, ensuring functional equivalence in all applications.

Frequently Asked Questions (FAQ)

Q: Can RAPC742X be used as a direct replacement for RAPC742?

A: Yes. The RAPC742X is a direct substitute. Both parts share identical electrical specifications (3 A current rating, tin-plated copper alloy contacts), mechanical dimensions (0.039" ID / 0.177" OD), contact configuration (2 conductors, 3 contacts with normally closed switch), mounting type (through-hole, right angle), and termination method (solder). Both are ROHS3 compliant and manufactured by Switchcraft Inc.

Q: What is the primary difference between RAPC742 and RAPC742X?

A: The primary difference is packaging. RAPC742 is supplied in standard packaging, while RAPC742X is supplied in bulk packaging. This distinction does not affect electrical or mechanical performance.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical RoHS3 compliance status and are manufactured to the same specifications by Switchcraft Inc.

Q: What parameters determine substitution compatibility for barrel connector jacks?

A: Substitution compatibility is determined by mating diameter (ID/OD), contact configuration (number of conductors and contacts), internal switch characteristics, mounting orientation, termination method, current rating, and contact/housing materials. All these parameters must match between the original and substitute part.
