3040-34-00 Equivalent & Substitute Parts

Part Overview

The 3040-34-00 is a 34-position ribbon cable DIP header connector with IDC termination, manufactured by CNC Tech. This through-hole mounted connector features a 0.050" (1.27mm) cable pitch and 0.100" (2.54mm) board-side pitch across 2 rows with 0.100" row spacing. The connector is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations.

Substitute Part Grouping Explanation

Substitution eligibility for the 3040-34-00 is determined by strict alignment of the following critical parameters:

• Connector Type: Ribbon Cable, DIP Header
• Number of Positions: 34
• Cable Pitch: 0.050" (1.27mm)
• Board-Side Pitch: 0.100" (2.54mm)
• Number of Rows: 2
• Row Spacing: 0.100" (2.54mm)
• Mounting Type: Through Hole
• Cable Termination: IDC
• Features: Feed Through
• Contact Finish: Gold
• Number of Positions Loaded: All
• RoHS Status: ROHS3 Compliant
• MSL: 1 (Unlimited)

The AWLP 34/3,2-G manufactured by Assmann WSW Components meets all critical electrical and mechanical parameters required for direct substitution. Differences in contact finish thickness specification and color designation do not affect functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

The AWLP 34/3,2-G is a direct functional equivalent to the 3040-34-00. Both connectors maintain identical electrical and mechanical specifications across all critical parameters. The primary advantage of selecting the AWLP 34/3,2-G is its active product status, ensuring continued availability and supply chain stability. Both parts maintain ROHS3 compliance and identical export classification (EAR99), supporting regulatory consistency in system designs. The substitute part is available in tray packaging, which may differ from the original part's packaging specification but does not affect connector performance or board-level integration.

Frequently Asked Questions (FAQ)

Q: Can the AWLP 34/3,2-G be used as a direct replacement for the 3040-34-00 in existing designs?

A: Yes. Both connectors share identical connector type, position count, pitch specifications, row configuration, mounting method, and termination type. The connectors are mechanically and electrically interchangeable at the board level.

Q: What is the significance of the color difference (Gray for AWLP 34/3,2-G)?

A: Color is a visual identifier and does not affect electrical performance or mechanical compatibility. The gray color designation of the AWLP 34/3,2-G does not impact substitution eligibility.

Q: Does the difference in contact finish thickness specification affect compatibility?

A: No. Both connectors feature gold contact finish. The flash thickness specification for the 3040-34-00 and the unspecified thickness for the AWLP 34/3,2-G do not affect electrical conductivity or connector mating characteristics.

Q: Why is product status relevant to substitution?

A: The 3040-34-00 is obsolete, meaning CNC Tech no longer manufactures this part. The AWLP 34/3,2-G maintains active status, ensuring long-term availability and supply continuity for new designs and system maintenance.

Q: Are there compliance or certification differences between these parts?

A: No. Both connectors are ROHS3 compliant, carry MSL rating of 1 (Unlimited), and share identical ECCN (EAR99) and HTSUS classifications.

Q: Does packaging affect the connector's performance?

A: No. Packaging is a logistics specification. The tray packaging of the AWLP 34/3,2-G does not affect the connector's electrical or mechanical performance in the application.
