Key Parameters

Substitute Part Grouping Explanation

The RA49C12A qualifies as a direct substitute for the RA70B12A based on the following critical parameters:

• Identical mating diameter: 6.35mm (0.250", 1/4") headphone jack
• Identical actual diameter: 0.253" (6.43mm)
• Identical signal configuration: Mono with 2 conductors and 3 contacts
• Identical internal switch configuration: Single switch
• Identical mounting type: Through hole, right angle
• Identical termination method: Solder
• Identical shielding: Unshielded
• Identical contact material plating: Silver
• Identical contact material: Copper alloy
• Identical housing material: Thermoplastic, polyester
• Identical thread size: 3/8"-32
• Identical regulatory compliance: ROHS3 compliant, REACH unaffected

The RA49C12A is manufactured by the same supplier (Switchcraft Inc.) within the same RA Jax® series, ensuring mechanical and electrical compatibility with applications designed for the RA70B12A.
