Switchcraft N114BPCX 6.35mm Stereo Phone Jack Connector - Equivalent & Substitute Parts

Part Overview

The Switchcraft N114BPCX is an active, panel-mount stereo phone jack connector designed for 6.35mm (1/4") headphone applications. This Hi-D® NL11 series connector features three-conductor TRS (Tip-Ring-Sleeve) configuration with solder termination and integrated mounting hardware. The connector is specified for audio and signal applications requiring reliable female jack connectivity with panel mounting capability. Substitute parts are identified to provide equivalent functionality when the primary part is unavailable or when alternative specifications better suit specific application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the N114BPCX is determined by strict equivalence across the following critical parameters:

• Connector type and gender (Phone Jack, Female)
• Mating diameter (6.35mm / 1/4" headphone standard)
• Signal configuration (Stereo, 3 Conductor TRS)
• Contact count (3 Conductors, 5 Contacts)
• Mounting configuration (Panel Mount, Through Hole)
• Internal switch count (Two Switches)
• Thread size (3/8"-32)
• Regulatory compliance (ROHS3, REACH Unaffected, EAR99)

The Amphenol Audio ACJS-MIV-5 meets all critical substitution criteria. Variations in contact material plating, housing material composition, and panel hole tolerance fall within acceptable mechanical and electrical equivalence for this connector category.

Parameter Comparison

Engineering Selection Recommendations

Both the Switchcraft N114BPCX and Amphenol Audio ACJS-MIV-5 are active products with identical regulatory compliance status (ROHS3 Compliant, REACH Unaffected, EAR99 classification). Selection between these parts is based on the following provided specifications:

The N114BPCX features tin-plated brass contacts with a polyester glass-filled housing and operates across -20°C to 65°C. The ACJS-MIV-5 provides gold-plated copper contacts with PBT housing and an extended operating range of -25°C to 70°C. The ACJS-MIV-5 termination uses solder eyelets rather than direct solder pads. Panel hole size tolerance differs by 0.007" (0.18mm), which is within standard mechanical manufacturing tolerances for panel-mount connectors.

Selection should be based on specific application requirements regarding contact plating preference, housing material compatibility, temperature operating range, and termination method compatibility with PCB design.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol Audio ACJS-MIV-5 directly replace the Switchcraft N114BPCX in existing designs?

A: The ACJS-MIV-5 is mechanically and electrically equivalent for 6.35mm stereo phone jack applications. The primary design consideration is termination method: the ACJS-MIV-5 uses solder eyelets while the N114BPCX uses direct solder pads. PCB layout must accommodate eyelet termination. Panel hole size tolerance differs by 0.007", which is within standard manufacturing tolerances.

Q: What are the key parameters that define substitution eligibility for 6.35mm stereo phone jack connectors?

A: Substitution eligibility requires equivalence in connector type (Phone Jack, Female), mating diameter (6.35mm), signal configuration (Stereo TRS), contact count (3 Conductors, 5 Contacts), mounting type (Panel Mount, Through Hole), internal switch count (Two Switches), and thread size (3/8"-32). Regulatory compliance (ROHS3, REACH, ECCN) must also match.

Q: How do contact material differences affect connector performance?

A: The N114BPCX uses tin-plated brass contacts; the ACJS-MIV-5 uses gold-plated copper contacts. Both materials are suitable for audio and signal applications. Gold plating provides enhanced corrosion resistance and lower contact resistance. Tin plating is standard for general-purpose audio applications. Material selection should align with application environmental conditions and contact durability requirements.

Q: Are there temperature range considerations when substituting these connectors?

A: The N114BPCX operates from -20°C to 65°C; the ACJS-MIV-5 operates from -25°C to 70°C. The ACJS-MIV-5 provides extended low-temperature and high-temperature capability. Applications requiring operation outside the N114BPCX range should specify the ACJS-MIV-5.

Q: What is the significance of housing material differences?

A: The N114BPCX uses polyester with glass filler; the ACJS-MIV-5 uses PBT (Polybutylene Terephthalate). Both materials provide mechanical strength and electrical insulation suitable for panel-mount applications. PBT offers superior chemical resistance and dimensional stability. Material selection should consider environmental exposure and mechanical stress requirements.

Q: Do both connectors include mounting hardware?

A: Both the N114BPCX and ACJS-MIV-5 include identical mounting hardware packages: 1 Connector, 1 Nut, 1 Washer per unit. Installation procedures are equivalent for panel-mount applications.
