H6034NLT Common Mode Choke Equivalent & Substitute Parts

Part Overview

The H6034NLT is a 2-line common mode choke (CMC) surface mount component manufactured by Pulse Electronics, designed for power line filtering applications. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement continuity. The H6034NLT features a vertical 8 gull wing package with 300mOhm DC resistance and operates across a 0°C to 70°C temperature range.

Substitute Part Grouping Explanation

Substitute parts for the H6034NLT are qualified based on the following criteria:

• Filter Type: Power Line (identical across all substitutes)
• Number of Lines: 2-line configuration (identical across all substitutes)
• Mounting Type: Surface Mount (identical across all substitutes)
• Package / Case: Vertical, 8 Gull Wing (identical across all substitutes)
• Physical Dimensions: 0.245" L x 0.365" W x 0.220" H maximum (identical across all substitutes)
• Moisture Sensitivity Level: MSL 1 (Unlimited) (identical across all substitutes)
• Operating Temperature: 0°C ~ 70°C (identical across all substitutes)
• DC Resistance (DCR): Allowable range 250mOhm to 350mOhm

All substitute parts maintain identical mechanical and thermal specifications, with variation only in DC resistance values within the acceptable range for this product category.

Parameter Comparison

Engineering Selection Recommendations

H6502NLT is recommended as the primary substitute for applications where lower DC resistance (250mOhm) is acceptable or beneficial. This part is active in production status and ROHS3 compliant, providing long-term supply assurance.

H6503NLT is recommended as a direct functional replacement, matching the original H6034NLT DC resistance specification of 300mOhm. This part is active in production status and ROHS3 compliant, offering the closest electrical equivalence to the obsolete original.

H6506NLT is recommended for applications where higher DC resistance (350mOhm) is within design tolerance. This part is active in production status and ROHS3 compliant.

All three substitute parts are available in Tape & Reel packaging, which is standard for production environments. The transition from the obsolete H6034NLT to any of these active alternatives ensures continued component availability and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can H6502NLT, H6503NLT, and H6506NLT be used interchangeably with H6034NLT?

A: These parts share identical mechanical, thermal, and packaging specifications. Substitution is determined by DC resistance requirements. H6503NLT matches the original 300mOhm specification exactly. H6502NLT (250mOhm) and H6506NLT (350mOhm) are suitable where the application design permits variation within this resistance range.

Q: What is the significance of the DC resistance difference between substitutes?

A: DC resistance affects power dissipation and insertion loss in the common mode choke. Lower resistance (H6502NLT at 250mOhm) reduces heat generation; higher resistance (H6506NLT at 350mOhm) increases it. Circuit design must accommodate the selected resistance value.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. H6502NLT, H6503NLT, and H6506NLT are all ROHS3 compliant. The original H6034NLT does not specify RoHS status due to its obsolete classification.

Q: What packaging formats are available for substitute parts?

A: All substitute parts are supplied in Tape & Reel (TR) packaging, standard for automated assembly processes. The original H6034NLT packaging format is not specified.

Q: Are there any thermal or temperature rating differences?

A: No. All parts, including the original and substitutes, operate across the identical 0°C to 70°C temperature range.

Q: Can I use these substitutes in new designs?

A: Yes. H6502NLT, H6503NLT, and H6506NLT are all active production parts suitable for new designs. They provide long-term supply continuity compared to the obsolete H6034NLT.
