RAPC752 Equivalent & Substitute Parts

Part Overview

The RAPC752 is a power barrel connector jack manufactured by Switchcraft Inc., designed for applications requiring a 0.70mm ID (0.028"), 2.35mm OD (0.093") EIAJ-1 standard connection. This through-hole, right-angle jack features solder termination and accommodates 2 conductors with 3 contacts, including a single normally closed switch. The connector is rated for 3A current and is constructed with a copper alloy contact material plated in silver, housed in black thermoplastic. With 1174 pieces in current inventory, the RAPC752 remains actively available for new designs and production requirements.

Identifying equivalent and substitute parts is essential for supply chain continuity, design flexibility, and managing component availability across manufacturing cycles.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RAPC752 is determined by strict adherence to the following critical parameters:

Mechanical Compatibility:

• Industry recognized mating diameter: 0.70mm ID (0.028"), 2.35mm OD (0.093") EIAJ-1
• Connector type: Jack
• Mounting configuration: Through hole, right angle orientation
• Termination method: Solder

Electrical Specifications:

• Number of positions/contacts: 2 conductors, 3 contacts
• Internal switching: Single switch, normally closed
• Current rating: 3 A minimum
• Contact material and plating: Copper alloy with silver plating

Regulatory & Environmental:

• RoHS3 compliance
• Moisture sensitivity level: 1 (unlimited)

Only parts meeting all of these criteria qualify as direct substitutes. Deviations in any parameter render a part incompatible for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

The RAPC752X qualifies as a direct substitute for the RAPC752 based on matching mechanical and electrical specifications within the EIAJ-1 0.70mm ID / 2.35mm OD barrel connector standard. Both parts are manufactured by Switchcraft Inc. and maintain identical connector type, contact configuration, mounting orientation, and termination method.

The RAPC752X carries active product status and maintains ROHS3 compliance with MSL 1 rating, confirming suitability for current production environments. The substitute part is available with 786 pieces in inventory, providing adequate supply for component selection decisions.

Selection between the main part and substitute should be based on inventory availability and procurement lead times, as both parts satisfy the specified electrical and mechanical requirements for applications requiring EIAJ-1 barrel jack connectors with solder termination.

Frequently Asked Questions (FAQ)

Q: What makes RAPC752X a valid substitute for RAPC752?

A: Both parts conform to the EIAJ-1 standard for 0.70mm ID / 2.35mm OD barrel connectors, share identical mechanical mounting (through-hole, right angle), use solder termination, and maintain the same contact configuration (2 conductors, 3 contacts). Both are manufactured by Switchcraft Inc. and carry active product status.

Q: Are there any dimensional differences between RAPC752 and RAPC752X?

A: The RAPC752X specifies actual diameter measurements of 0.026" (0.65mm ID) and 0.108" (2.75mm OD). The main part RAPC752 does not provide actual diameter specifications in the available data. Both conform to the EIAJ-1 industry standard of 0.70mm ID / 2.35mm OD.

Q: What is the current rating for these connectors?

A: The RAPC752X is rated for 3 A continuous current. This specification applies to applications using either the main part or substitute.

Q: Are both parts RoHS compliant?

A: The RAPC752X is ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level), confirming suitability for modern manufacturing and environmental standards.

Q: How do inventory levels compare?

A: The RAPC752 has 1174 pieces in current stock, while the RAPC752X has 786 pieces available. Both maintain adequate inventory for production requirements.

Q: Can these connectors be used interchangeably in existing designs?

A: Yes. Both parts meet the EIAJ-1 barrel connector standard and maintain identical electrical and mechanical specifications for jack-type connectors with solder termination and right-angle mounting.
