Hammond Manufacturing 602A Pulse Transformer Equivalent & Substitute Parts

Part Overview

The Hammond Manufacturing 602A is a 2.06mH isolation and data interface encapsulated pulse transformer with a 1:1:1 turns ratio, designed for through-hole mounting applications. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations. The 602A's compact form factor (0.500" L x 0.350" W, 0.250" seated height) and ROHS3 compliance establish the baseline specifications for substitute evaluation.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Hammond 602A is determined by strict alignment with the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Inductance value: 2.06mH (exact match required)
• Turns ratio: 1:1:1 (exact match required)
• Mounting configuration: Through hole (exact match required)
• Physical footprint: 0.500" L x 0.350" W maximum (exact match required)
• Seated height: ≤0.250" (must not exceed original specification)

Secondary Compliance Requirements:

• RoHS3 compliance status
• REACH unaffected classification
• Encapsulated construction for isolation applications

The Murata Power Solutions Inc. 76602/1C meets all primary electrical and mechanical criteria. Both components share identical inductance (2.06mH), turns ratio (1:1:1), footprint dimensions, and through-hole mounting configuration. The 76602/1C seated height of 0.260" exceeds the 602A specification by 0.010", representing a marginal dimensional variance within typical PCB layout tolerances for through-hole components. Both parts maintain ROHS3 and REACH compliance.

Parameter Comparison

Engineering Selection Recommendations

The Murata Power Solutions Inc. 76602/1C qualifies as a direct functional substitute for the Hammond 602A based on matching electrical specifications (2.06mH inductance, 1:1:1 turns ratio) and identical through-hole footprint dimensions. Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent component selection.

The 76602/1C's active product status provides supply chain continuity and technical support availability, addressing the obsolescence constraint of the 602A. The 0.010" seated height variance (0.260" vs. 0.250") falls within standard PCB layout tolerances for through-hole components and does not preclude mechanical compatibility in standard applications.

Selection of the 76602/1C is appropriate for direct replacement in existing designs and for new implementations requiring 2.06mH pulse transformer functionality with isolation and data interface characteristics.

Frequently Asked Questions (FAQ)

Q: Can the Murata 76602/1C directly replace the Hammond 602A in existing PCB designs?

A: Yes. Both components share identical inductance (2.06mH), turns ratio (1:1:1), and through-hole footprint dimensions (0.500" L x 0.350" W). The 76602/1C seated height of 0.260" exceeds the 602A specification by 0.010", which is within standard PCB layout tolerances for through-hole components.

Q: What are the critical parameters for substitution eligibility?

A: Inductance value (2.06mH), turns ratio (1:1:1), mounting type (through hole), and physical footprint (0.500" x 0.350") must match exactly. Seated height must not exceed 0.250" by more than typical manufacturing tolerances.

Q: Are there compliance differences between the 602A and 76602/1C?

A: No. Both components are ROHS3 compliant and REACH unaffected, meeting identical regulatory requirements.

Q: Why is the Hammond 602A listed as obsolete?

A: Obsolescence indicates the component is no longer in active production. The Murata 76602/1C provides functional equivalence with active product status and ongoing supply availability.

Q: Does the ET (Volt-Time) specification of 17.5VµS for the 76602/1C affect substitution suitability?

A: The ET specification is provided for the 76602/1C but not specified for the 602A. This parameter does not disqualify substitution, as the primary electrical criteria (inductance and turns ratio) are identical.

Q: What packaging format is the 76602/1C supplied in?

A: The 76602/1C is supplied in tube packaging, standard for through-hole transformer components.
