RAPC722 Equivalent & Substitute Parts

Part Overview

The RAPC722 is a power barrel connector jack manufactured by Switchcraft Inc., designed for through-hole, right-angle mounting applications. This connector features a 2.00mm ID (0.079") and 5.50mm OD (0.217") barrel configuration with solder eyelet termination, supporting up to 5 amperes. The RAPC722 is classified as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement continuity.

Substitute Part Grouping Explanation

The RAPC722X qualifies as a direct substitute based on the following critical parameters:

Connector type, gender, and mating diameter specifications are identical
Contact configuration (2 conductors, 3 contacts) matches exactly
Internal switch function (single switch, normally closed) is preserved
Mounting type (through hole, right angle) and termination method (solder eyelet) are equivalent
Current rating (5 A) and contact materials (silver plating, brass base) are maintained
Housing material (thermoplastic) and body color (black) are consistent
Shielding classification (unshielded) remains unchanged

Minor dimensional variance in actual diameter (RAPC722: 0.248" OD vs. RAPC722X: 0.248" OD; RAPC722: 0.079" ID vs. RAPC722X: 0.076" ID) falls within acceptable mechanical tolerance for barrel connector applications and does not affect functional compatibility.

Engineering Selection Recommendations

The RAPC722X is the active equivalent for the obsolete RAPC722. Selection of RAPC722X is supported by the following factors:

Product status: RAPC722X is active and currently manufactured, ensuring long-term availability and supply chain stability
Regulatory compliance: RAPC722X meets ROHS3 compliance requirements, whereas RAPC722 is non-compliant
Functional equivalence: All critical electrical and mechanical parameters are preserved
Moisture sensitivity: RAPC722X carries MSL 1 (unlimited), indicating superior handling flexibility compared to the RAPC722

For new designs or redesigns of existing products using RAPC722, RAPC722X is the appropriate selection. For legacy systems currently using RAPC722, transition to RAPC722X is recommended to align with current regulatory standards and ensure procurement continuity.

Frequently Asked Questions (FAQ)

Q: Can RAPC722X be used as a direct replacement for RAPC722 in existing assemblies?

A: Yes. RAPC722X maintains identical connector type, mating diameter, contact configuration, mounting type, and termination method. The minor dimensional variance in actual ID (0.079" vs. 0.076") is within acceptable mechanical tolerance for barrel connector applications and does not affect functional compatibility or mating performance.

Q: What is the primary reason to transition from RAPC722 to RAPC722X?

A: RAPC722 is classified as obsolete, creating procurement risk. RAPC722X is an active product with equivalent electrical and mechanical specifications. Additionally, RAPC722X meets ROHS3 compliance, whereas RAPC722 does not.

Q: Are there packaging differences between RAPC722 and RAPC722X?

A: RAPC722 packaging is not specified in available data. RAPC722X is supplied in bulk packaging. Confirm packaging requirements with your procurement or supply chain team.

Q: Do the RoHS compliance differences affect electrical performance?

A: No. RoHS compliance reflects manufacturing process and material composition standards, not electrical performance. Both parts maintain identical current rating (5 A), contact materials (silver-plated brass), and electrical characteristics.

Q: Is RAPC722X suitable for high-moisture environments?

A: RAPC722X carries MSL 1 (unlimited), indicating no moisture sensitivity restrictions. However, the connector itself is unshielded. Environmental protection depends on application-level design considerations, not the connector's MSL rating.
