RA70C12A Equivalent & Substitute Parts
Part Overview
The RA70C12A is a 6.35mm (0.250", 1/4") mono headphone jack connector manufactured by Switchcraft Inc. under the RA Jax® series. This right-angle, through-hole solder connector features a single internal switch and is designed for audio applications requiring a standard headphone jack interface. The part is currently obsolete, making equivalent substitutes necessary for new designs and ongoing production requirements.

Substitute Part Grouping Explanation
The SJ-63062B from CUI Devices qualifies as a functional equivalent to the RA70C12A based on the following critical parameters:
- Mating Diameter Match: Both connectors use the industry-standard 6.35mm (0.250", 1/4") headphone jack interface
- Signal Configuration: Both are mono connectors with identical contact architecture (2 conductors, 3 contacts)
- Gender and Mounting: Both are female connectors with right-angle, through-hole solder termination
- Internal Switch Function: Both feature a single internal switch for audio signal routing
- Contact Material: Both use silver-plated contacts for reliable electrical connection
- Compliance: Both are ROHS3 compliant and REACH unaffected
The substitution is valid for applications where the RA70C12A's obsolete status necessitates an active alternative with equivalent electrical and mechanical interface characteristics.

Engineering Selection Recommendations
The SJ-63062B is the appropriate substitute for the obsolete RA70C12A in new designs and production applications. Both connectors maintain identical electrical interface specifications and mechanical mounting characteristics. The SJ-63062B offers the advantage of active product status, ensuring ongoing availability and supply chain continuity. Both parts meet current regulatory requirements with ROHS3 compliance and REACH unaffected status, making them suitable for applications subject to environmental and hazardous substance restrictions.
Frequently Asked Questions (FAQ)
Q: Can the SJ-63062B directly replace the RA70C12A in existing designs?
A: Yes. Both connectors share identical mating diameter (6.35mm), signal configuration (mono), contact architecture (2 conductors, 3 contacts), mounting type (through-hole right angle), and termination method (solder). The physical and electrical interfaces are equivalent.
Q: What are the key differences between these two connectors?
A: The primary differences are product status (RA70C12A is obsolete; SJ-63062B is active), housing material (RA70C12A uses thermoplastic polyester; SJ-63062B uses polybutylene terephthalate), and additional features on the SJ-63062B (cover, mounting hardware, thread lock). The SJ-63062B also includes rated operating temperature (-25°C to 70°C), voltage rating (12VDC), and current rating (1A) specifications.
Q: Are there any mechanical compatibility concerns?
A: Thread size differs between the two connectors (RA70C12A uses 3/8"-32; SJ-63062B uses M12). Panel hole sizing and mounting hardware may require adjustment during integration. Verify mechanical fit within your specific application before production implementation.
Q: Do both connectors meet current compliance standards?
A: Yes. Both the RA70C12A and SJ-63062B are ROHS3 compliant and REACH unaffected, meeting current environmental and hazardous substance regulations.
Q: What is the packaging difference?
A: The RA70C12A is supplied with individual connector packaging including a nut and washer. The SJ-63062B is supplied in bag packaging without additional hardware specifications listed.
