Amphenol ICC 68021-272 Rectangular Connector: Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 68021-272 is a right-angle rectangular header connector with 72 positions at 2.54mm pitch, designed for through-hole board-to-board applications. This connector belongs to the BERGSTIK® II series and is classified as obsolete. Due to its discontinued status, identifying functionally equivalent substitute parts is essential for design continuity, maintenance, and production support. Substitute connectors must maintain compatibility across pitch, position count, mounting style, and electrical ratings to ensure reliable performance in existing or legacy circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 68021-272 is determined by the following critical parameters:

Primary Matching Criteria:

• Pitch - Mating: 0.100" (2.54mm) — must be identical
• Number of Positions: 72 — must be identical
• Number of Rows: 2 — must be identical
• Row Spacing - Mating: 0.100" (2.54mm) — must be identical
• Mounting Type: Through Hole, Right Angle — must be identical
• Contact Type: Male Pin — must be identical
• Termination: Solder — must be identical

Secondary Compatibility Parameters:

• Current Rating: 3A per Contact — minimum acceptable
• Operating Temperature Range: must encompass or match the original range
• Connector Style: Board to Board or Board to Board/Cable compatible
• Material Flammability Rating: UL94 V-0 — preferred for safety compliance

Three substitute parts meet the primary matching criteria while maintaining electrical and mechanical compatibility:

1. 802-V3-072-20-001101 (Preci-Dip) — Exact position and pitch match; active product status; RoHS3 compliant
2. M20-9743646 (Harwin Inc.) — Exact position and pitch match; active product status; RoHS3 compliant; cuttable feature
3. 4-103326-0 (TE Connectivity AMP Connectors) — 80-position variant; position count differs; included as reference for higher-density applications

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: 802-V3-072-20-001101 (Preci-Dip)

This connector is the optimal substitute for the 68021-272. It matches all critical mechanical and electrical parameters: 72 positions, 2.54mm pitch, 2-row configuration, through-hole right-angle mounting, and 3A current rating. The part is currently active in production, ensuring long-term availability. RoHS3 compliance provides regulatory advantage for new designs and manufacturing environments with RoHS requirements. Operating temperature range of -55°C to 125°C covers the original specification. Gold mating contact finish and brass contact material provide equivalent electrical performance to the original phosphor bronze construction.

Secondary Recommendation: M20-9743646 (Harwin Inc.)

This connector provides an alternative with identical position and pitch specifications. Active product status and RoHS3 compliance match the Preci-Dip option. The cuttable feature offers design flexibility for applications requiring custom connector lengths. Operating temperature range of -40°C to 105°C is narrower than the original but suitable for most commercial and industrial applications. Tin mating contact finish differs from the original gold specification; verify compatibility with mating connector contact materials in high-reliability applications.

Reference Option: 4-103326-0 (TE Connectivity AMP Connectors)

This 80-position connector is included as a reference for applications requiring higher pin density. While it exceeds the original 72-position specification, it maintains the 2.54mm pitch and through-hole right-angle mounting. This option is suitable only if circuit design can accommodate the additional 8 positions. Product status is obsolete; availability may be limited.

Frequently Asked Questions (FAQ)

Q: Can I use the 802-V3-072-20-001101 as a direct replacement for the 68021-272?

A: Yes. Both connectors share identical pitch (2.54mm), position count (72), row configuration (2 rows), mounting style (through-hole right-angle), and current rating (3A per contact). Mechanical and electrical compatibility is confirmed. Verify mating connector compatibility with the gold contact finish specification.

Q: What is the difference between the Preci-Dip and Harwin substitutes?

A: Both meet the core mechanical specifications. The Preci-Dip 802-V3-072-20-001101 features gold mating contacts and operates across -55°C to 125°C. The Harwin M20-9743646 features tin mating contacts, operates across -40°C to 105°C, and includes a cuttable design feature. Select based on temperature requirements and contact finish compatibility with your mating connector.

Q: Why is the TE Connectivity 4-103326-0 listed if it has 80 positions instead of 72?

A: The 4-103326-0 is included as a reference option for applications where higher pin density is acceptable. It maintains pitch and mounting compatibility but exceeds the original position count. Use this option only if your circuit design can utilize the additional 8 positions.

Q: Are the substitute parts RoHS compliant?

A: The Preci-Dip 802-V3-072-20-001101 and Harwin M20-9743646 are both RoHS3 compliant. The original 68021-272 is RoHS non-compliant. If your application or manufacturing environment requires RoHS compliance, select one of the active substitute parts.

Q: What is the operating temperature difference between the original and substitutes?

A: The original 68021-272 operates from -65°C to 125°C. The Preci-Dip substitute operates from -55°C to 125°C (10°C reduction at the lower limit). The Harwin substitute operates from -40°C to 105°C (25°C reduction at both limits). Verify that the substitute temperature range meets your application requirements.

Q: Can I mix contact finishes between the original and substitute connectors?

A: The original 68021-272 uses gold or gold GXT™ mating contacts. The Preci-Dip substitute uses gold; the Harwin substitute uses tin. Verify compatibility between mating connector contact materials. Gold-to-gold and gold-to-tin interfaces are generally acceptable; tin-to-tin is preferred for optimal contact reliability.

Q: What is the difference between the contact materials?

A: The original uses phosphor bronze; the substitutes use brass. Both materials provide adequate electrical conductivity and mechanical durability for 3A per contact applications. Brass offers improved corrosion resistance in certain environments. No functional difference exists for standard board-to-board applications.

Q: Is the 68021-272 still available?

A: The 68021-272 is classified as obsolete. Current inventory is limited (768 pieces reported). For new designs or long-term production support, transition to an active substitute part such as the Preci-Dip 802-V3-072-20-001101 or Harwin M20-9743646.
