Substitute Categories:

Category 1: Direct Molex Impact Series Equivalents Parts 0760555606 and 0760559606 are direct functional equivalents within the Molex Impact 76055 series. These maintain identical electrical and mechanical specifications including 0.053" (1.35mm) pitch, 240-position layout, and operating parameters. Both are active products with current manufacturing status.

Category 2: TE Connectivity Cross-Manufacturer Substitutes Parts 1934331-1, 1934332-1, 1934333-1, and 1934334-1 are TE Connectivity Z-PACK TinMan series headers rated for 240 positions with identical row/column configuration and through-hole press-fit mounting. These substitutes operate at higher voltage (250V vs. 30V) and current (0.5A) ratings with extended temperature range (-65°C to 90°C). Pitch specification differs at 0.075" (1.90mm), requiring PCB layout verification before implementation.

Engineering Selection Recommendations

For Direct Replacement (Preferred): Select Molex 0760555606 or 0760559606 for applications requiring identical electrical and mechanical specifications. Both parts are active products with current manufacturing support, ROHS3 compliance, and UL94 V-0 certification. These substitutes maintain the 0.053" (1.35mm) pitch and 30V voltage rating of the original design without PCB layout modification.

For Cross-Manufacturer Substitution: TE Connectivity parts 1934331-1, 1934332-1, 1934333-1, and 1934334-1 are suitable only when design specifications accommodate the following parameter differences:

Pitch change from 0.053" (1.35mm) to 0.075" (1.90mm) requires PCB footprint redesign
Voltage rating increase from 30V to 250V is compatible with lower-voltage applications
Current rating of 0.5A per contact provides additional electrical capacity
Extended temperature range (-65°C to 90°C) exceeds original specification

All substitute parts maintain UL94 V-0 flammability rating and RoHS compliance. TE parts 1934332-1 and 1934334-1 carry RoHS Compliant status; parts 1934331-1 and 1934333-1 are ROHS3 Compliant.

Frequently Asked Questions (FAQ)

Q: Can I use Molex 0760555606 or 0760559606 as direct drop-in replacements? A: Yes. Both parts are functionally equivalent to the 0760558606 with identical pitch (0.053"/1.35mm), position count (240), configuration (15×16), voltage rating (30V), and operating temperature range (-55°C to 85°C). No PCB layout changes are required. Both are active products with current manufacturing availability.

Q: What is the primary difference between Molex Impact series and TE Z-PACK TinMan substitutes? A: The TE parts operate at 0.075" (1.90mm) pitch versus 0.053" (1.35mm) for Molex Impact series. This pitch difference requires PCB footprint redesign. TE parts also provide higher voltage (250V) and current (0.5A) ratings with extended temperature range (-65°C to 90°C).

Q: Are TE Connectivity 1934331-1, 1934332-1, 1934333-1, and 1934334-1 interchangeable with each other? A: These four TE parts share identical electrical and mechanical specifications within the Z-PACK TinMan series. Differences exist only in RoHS certification status: parts 1934332-1 and 1934334-1 are RoHS Compliant, while 1934331-1 and 1934333-1 are ROHS3 Compliant. Selection depends on regulatory requirements for the end application.

Q: What packaging formats are available for substitutes? A: Molex 0760555606 and 0760559606 are supplied in Tray packaging. TE Connectivity parts 1934331-1, 1934332-1, 1934333-1, and 1934334-1 are supplied in Tube packaging. Packaging selection may affect procurement logistics and handling procedures.

Q: Can I use a TE substitute if my PCB is designed for 0.053" (1.35mm) pitch? A: No. TE Z-PACK TinMan parts operate at 0.075" (1.90mm) pitch. Using these parts on a PCB designed for 0.053" (1.35mm) pitch will result in misalignment and connection failure. PCB redesign is required for TE part implementation.

Q: Are all substitute parts RoHS compliant? A: Yes. All listed substitutes meet RoHS requirements. Molex parts and TE parts 1934331-1 and 1934333-1 are ROHS3 Compliant. TE parts 1934332-1 and 1934334-1 are RoHS Compliant. Both compliance levels are acceptable for most applications; verify specific regulatory requirements for your end market.
