A-DFF 09 LPIII/Z-UNC Equivalent & Substitute Parts

Part Overview

The A-DFF 09 LPIII/Z-UNC is a 9-position D-Sub receptacle connector manufactured by Assmann WSW Components, designed for IDC ribbon cable termination in free-hanging inline applications. This connector features female sockets with gold-plated contacts, steel tin-plated shell, and operates across -55°C to 105°C. The part is currently active in production with 1040 units in stock.

Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in applications where the primary part becomes unavailable or when alternative sourcing is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the A-DFF 09 LPIII/Z-UNC is determined by strict alignment of the following parameters:

• Connector style and type (D-Sub receptacle, female sockets)
• Position count and shell size (9 positions, DE/E layout)
• Mounting configuration (free-hanging inline)
• Termination method (IDC ribbon cable)
• Shell material and finish (steel, tin plated)
• Contact finish (gold plated)
• Dielectric material (PBT, glass filled)
• Compliance certifications (ROHS3, REACH Unaffected)

The substitute part DE09-SF-M2 from Adam Tech meets all these criteria, enabling direct functional replacement in applications requiring 9-position D-Sub IDC receptacle connectors with equivalent mechanical and electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the A-DFF 09 LPIII/Z-UNC and DE09-SF-M2 are active production components with ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements for electronic component procurement.

The DE09-SF-M2 substitute provides an extended operating temperature range (-65°C to 125°C versus -55°C to 105°C) and higher current rating (5A versus 3A), making it suitable for applications requiring broader thermal or power delivery specifications. Both parts share identical mechanical interfaces, shell configurations, and termination methods, ensuring direct compatibility in IDC ribbon cable connector applications.

Selection between these parts should be based on specific application requirements regarding current capacity and operating temperature envelope, with both options meeting the core D-Sub 9-position receptacle specification.

Frequently Asked Questions (FAQ)

Q: Can DE09-SF-M2 be used as a direct replacement for A-DFF 09 LPIII/Z-UNC?

A: Yes. Both connectors share identical mechanical form factors, shell sizes (DE/E layout), mounting configurations (free-hanging inline), and IDC ribbon cable termination methods. The DE09-SF-M2 meets all core substitution criteria for 9-position D-Sub receptacle applications.

Q: What are the key differences between these two parts?

A: The primary differences are operating temperature range (DE09-SF-M2: -65°C to 125°C versus A-DFF 09 LPIII/Z-UNC: -55°C to 105°C), current rating (DE09-SF-M2: 5A versus A-DFF 09 LPIII/Z-UNC: 3A), and contact material (DE09-SF-M2: Phosphor Bronze versus A-DFF 09 LPIII/Z-UNC: Copper Alloy). Electrical and mechanical interfaces remain equivalent.

Q: Are both parts RoHS compliant?

A: Yes. Both A-DFF 09 LPIII/Z-UNC and DE09-SF-M2 are ROHS3 compliant and REACH Unaffected, meeting current environmental and regulatory standards for electronic component use.

Q: What wire gauges are supported?

A: A-DFF 09 LPIII/Z-UNC supports 26-28 AWG ribbon cable, while DE09-SF-M2 supports 28-30 AWG. Applications using 28 AWG ribbon cable are compatible with both connectors.

Q: Do these connectors require any special handling or storage?

A: Both parts have MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard electronic component storage practices apply.
