EB65-P0K1830X Card Edge Connector Equivalent & Substitute Parts

Part Overview

The EB65-P0K1830X is a 36-position female card edge connector manufactured by Vishay Dale, designed for dual-edge applications with 0.125" (3.18mm) pitch spacing. This connector features wire wrap termination and phosphor bronze contacts with gold finish, rated for operating temperatures from -65°C to 125°C. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EB65-P0K1830X is determined by the following critical parameters:

Primary Compatibility Criteria:

• Number of positions: 36 (fixed requirement)
• Pitch spacing: 0.125" (3.18mm) (fixed requirement)
• Gender: Female (fixed requirement)
• Card configuration: Dual edge, 2 rows × 18 positions per row (fixed requirement)
• Mounting type: Through hole (fixed requirement)
• Contact material: Phosphor bronze (fixed requirement)
• Contact finish: Gold (fixed requirement)
• Operating temperature range: -65°C to 125°C minimum (fixed requirement)

Allowable Variations:

• Card thickness acceptance range (connector must accommodate 0.054" ~ 0.071")
• Termination method (wire wrap vs. solder acceptable)
• Contact type (cantilever vs. loop bellows acceptable)
• Insulation material (PPS vs. polyamide acceptable)
• Color (brown vs. black acceptable)
• Flange mounting configuration (top mount opening vs. flush mount acceptable)
• RoHS and compliance status (active products preferred over obsolete)

The substitute part GBA18DTKD meets all primary compatibility criteria while offering improved product status and modern compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The GBA18DTKD from Sullins Connector Solutions is the qualified substitute for the obsolete EB65-P0K1830X. Selection is based on the following engineering factors:

Functional Equivalence: Both connectors maintain identical electrical and mechanical specifications for the critical parameters: 36 positions, 0.125" pitch, dual-edge female configuration, through-hole mounting, phosphor bronze gold-plated contacts, and -65°C to 125°C operating temperature range.

Product Status Advantage: The GBA18DTKD is an active product with current manufacturing support, whereas the EB65-P0K1830X is obsolete. This ensures long-term component availability and supply chain continuity.

Compliance Status: The GBA18DTKD is ROHS3 compliant and REACH unaffected, meeting modern regulatory requirements. The original EB65-P0K1830X is RoHS non-compliant, making the substitute preferable for new designs and systems requiring compliance documentation.

Termination Compatibility: While the original uses wire wrap termination and the substitute uses solder termination, both methods provide equivalent electrical and mechanical performance for this connector class. PCB layout and assembly processes must be adjusted accordingly.

Contact Type Variation: The substitute employs loop bellows contacts versus the original's cantilever design. Both contact types deliver equivalent contact force and reliability within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can the GBA18DTKD directly replace the EB65-P0K1830X without PCB modifications?

A: The connectors are mechanically and electrically compatible in terms of mating interface and pin configuration. However, termination method differs (solder vs. wire wrap), requiring PCB footprint adjustment. The card thickness acceptance range of the GBA18DTKD (0.062") falls within the original specification (0.054" ~ 0.071"), ensuring proper card engagement.

Q: What is the difference between wire wrap and solder termination for this connector?

A: Wire wrap termination uses mechanical wrapping of wire around square posts, while solder termination uses plated through-holes for PCB soldering. Both methods provide equivalent electrical performance and reliability. Selection depends on assembly process capability and PCB design.

Q: Are the contact types (cantilever vs. loop bellows) functionally equivalent?

A: Yes. Both contact types are designed to provide consistent contact force and electrical conductivity within the operating temperature range. Loop bellows contacts offer slightly different mechanical compliance characteristics but maintain equivalent performance for this connector application.

Q: Does the insulation material change affect performance?

A: Both materials (PPS glass-filled and PA9T nylon) meet the operating temperature range of -65°C to 125°C and provide equivalent electrical insulation properties. The material change does not affect connector functionality or compatibility.

Q: Why is RoHS compliance important for this substitution?

A: RoHS3 compliance ensures the connector meets current environmental and regulatory standards for lead-free manufacturing. For systems requiring compliance documentation or operating in regulated markets, the GBA18DTKD is the appropriate choice.

Q: Is the GBA18DTKD available in the same packaging as the original?

A: The GBA18DTKD is supplied in tray packaging, whereas the original EB65-P0K1830X packaging is not specified. Verify packaging requirements for your procurement and assembly processes.
