Switchcraft C11Z Equivalent & Substitute Parts Reference

Part Overview

The Switchcraft C11Z is a 6.35mm (0.250", 1/4") mono headphone phone jack connector designed for panel mount applications with solder eyelet termination. This connector features the LITTEL-JAX® series designation and includes mounting hardware with thread lock capability. The C11Z is currently classified as obsolete, making identification of compatible substitute parts essential for ongoing maintenance, repair, and legacy system support where this connector type remains in use.

Key Parameters

Substitute Part Grouping Explanation

The Switchcraft C11X serves as a direct substitute for the obsolete C11Z based on strict electrical and mechanical parameter equivalence. Substitution is valid when the following criteria are met:

Critical Matching Parameters:

• Connector type: Phone Jack (Female gender)
• Signal configuration: Mono (2 conductors, 2 contacts)
• Mating diameter: 6.35mm (0.250", 1/4")
• Mounting configuration: Panel Mount with solder eyelet termination
• Panel hole size: 0.375" (9.52mm)
• Thread size: 3/8"-32
• Electrical ratings: 25VDC, 1 A minimum
• Operating temperature range: -20°C ~ 65°C minimum
• Features: Mounting hardware and thread lock included

The C11X maintains all specified electrical and mechanical parameters required for direct substitution in applications originally designed for the C11Z connector.

Parameter Comparison

Engineering Selection Recommendations

The Switchcraft C11X is the appropriate substitute for the obsolete C11Z connector. Both parts are manufactured by Switchcraft Inc. within the LITTEL-JAX® series and maintain identical electrical and mechanical specifications across all critical parameters.

The C11X offers the advantage of active product status, ensuring ongoing availability and supply chain reliability. The C11X carries ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for new designs and legacy system replacements.

Selection of the C11X over the C11Z is based on product lifecycle status and regulatory compliance. No electrical or mechanical redesign is required when substituting the C11X in applications originally specified for the C11Z.

Frequently Asked Questions (FAQ)

Q: Can the C11X be used as a direct replacement for the C11Z in existing designs?

A: Yes. The C11X maintains identical electrical ratings (25VDC, 1 A), mechanical dimensions (6.35mm mating diameter, 0.375" panel hole, 3/8"-32 thread), termination method (solder eyelet), and operating temperature range (-20°C ~ 65°C). No circuit modifications or mechanical redesign is necessary.

Q: What is the primary difference between the C11Z and C11X?

A: The C11Z is obsolete, while the C11X is an active product. Both connectors are functionally equivalent. The C11X additionally carries ROHS3 compliance and REACH unaffected certification.

Q: Are the mounting hardware and accessories identical between C11Z and C11X?

A: Yes. Both connectors include 3 pieces per unit: 1 connector, 1 nut, and 1 washer. Thread lock features are present on both models.

Q: What packaging options are available for the C11X?

A: The C11X is supplied in bulk packaging, suitable for production and repair applications.

Q: Are there any electrical parameter differences that would affect circuit performance?

A: No. Both the C11Z and C11X are rated for 25VDC at 1 A maximum current and operate across the identical temperature range of -20°C ~ 65°C. Signal configuration remains mono (2 conductors, 2 contacts) with unshielded design on both models.
