SN70B12A Equivalent & Substitute Parts

Part Overview

The SN70B12A is a 6.35mm (0.250", 1/4") mono headphone jack connector manufactured by Switchcraft Inc. in the barrel connectors category. This right-angle solder-mount connector features a single internal switch and is designed for audio applications requiring standard headphone jack connectivity. The part is currently in active inventory status with 770 units available as new original stock.

Substitute parts become necessary when primary inventory is depleted, when bulk packaging requirements differ from available stock, or when alternative sourcing from the same manufacturer's product line is required to meet project timelines and procurement specifications.

Substitute Part Grouping Explanation

The RN112APC qualifies as a direct substitute for the SN70B12A based on the following critical parameters that determine functional and mechanical compatibility:

Matching Parameters:

  • Connector Type: Phone Jack (Female)
  • Signal Configuration: Mono
  • Mating Diameter: 6.35mm (0.250", 1/4") - Headphone
  • Contact Count: 2 Conductors, 3 Contacts
  • Internal Switch Configuration: Single Switch
  • Mounting Type: Through Hole, Right Angle
  • Termination Method: Solder
  • Shielding: Unshielded
  • Contact Material Plating: Silver
  • Housing Material: Thermoplastic
  • Contact Material: Copper Alloy
  • Panel Hole Size: 0.375" (9.52mm)
  • Thread Size: 3/8"-32

Both connectors are manufactured by Switchcraft Inc. and maintain identical electrical and mechanical specifications for audio jack applications. The primary difference is packaging format: SN70B12A is supplied in standard packaging, while RN112APC is supplied in bulk packaging and includes mounting hardware (1 connector, 1 nut, 1 washer per unit).

Engineering Selection Recommendations

Both the SN70B12A and RN112APC are active products from Switchcraft Inc. with identical electrical and mechanical specifications for 6.35mm mono headphone jack applications. Selection between these parts should be based on the following criteria:

SN70B12A Selection: Choose this part number when standard packaging quantities are required and inventory availability is the primary consideration. Current stock of 770 units supports immediate procurement.

RN112APC Selection: Choose this part number when bulk packaging is specified in procurement requirements or when larger order quantities are needed. The RN112APC provides 1,938 units in current inventory and includes integrated mounting hardware (nut and washer), reducing assembly component count. This part carries explicit ROHS3 compliance and REACH unaffected certifications.

Both parts maintain identical connector specifications and are directly interchangeable at the circuit board level. The choice between them is driven by packaging format, inventory availability, and compliance documentation requirements rather than functional performance differences.

Frequently Asked Questions (FAQ)

Q: Can RN112APC be used as a direct replacement for SN70B12A in existing designs?

A: Yes. Both connectors share identical electrical and mechanical specifications including connector type, gender, signal configuration, mating diameter, contact count, mounting type, and termination method. No circuit board redesign or connector interface modification is required.

Q: What is the difference between SN70B12A and RN112APC?

A: The primary differences are packaging format and included hardware. SN70B12A uses standard packaging, while RN112APC is supplied in bulk packaging and includes mounting hardware (nut and washer) with each connector. Both are manufactured by Switchcraft Inc. and maintain identical connector specifications.

Q: Are the panel hole sizes and thread specifications identical?

A: Yes. Both connectors use a 0.375" (9.52mm) panel hole size and 3/8"-32 thread size, ensuring identical panel mounting compatibility.

Q: Does RN112APC include compliance certifications that SN70B12A does not?

A: RN112APC carries explicit ROHS3 compliance and REACH unaffected certifications in the provided documentation. Compliance status for SN70B12A was not specified in the available data.

Q: Which part should be selected for high-volume production?

A: RN112APC is recommended for high-volume applications due to bulk packaging availability and higher current inventory (1,938 units versus 770 units). The included mounting hardware also reduces secondary component procurement requirements.

Q: Are both connectors suitable for audio headphone jack applications?

A: Yes. Both connectors are designed for 6.35mm (0.250", 1/4") headphone jack applications with mono signal configuration and single internal switch operation.
