AEDT-8111-H14 Rotary Encoder Optical 400PPR Equivalent & Substitute Parts

Part Overview

The AEDT-8111-H14 is an optical rotary encoder manufactured by Broadcom Limited, designed for applications requiring precise rotational position feedback. This encoder delivers 400 pulses per revolution with quadrature output and index signal, operating at 5V supply voltage. The part features a 5mm open center actuator and chassis mount configuration suitable for motor and industrial equipment integration.

The AEDT-8111-H14 is classified as obsolete. Identifying equivalent and substitute parts is essential for maintaining system functionality in applications where original inventory is depleted or long-term supply continuity cannot be assured.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AEDT-8111-H14 are qualified based on strict electrical and mechanical parameter alignment. The following criteria determine substitution eligibility:

Critical Parameters for Substitution:

• Encoder Type: Optical
• Output Type: Quadrature with Index (Incremental)
• Pulses per Revolution: 400
• Voltage - Supply: 5V
• Actuator Type: 5mm Open Center
• Mounting Type: Chassis Mount, Motors
• Termination Style: Terminal Pins

Both identified substitute parts—AEDB-9140-H14 and HEDS-5540#H14—satisfy all critical electrical and mechanical parameters. Both are manufactured by Broadcom Limited and maintain functional equivalence with the obsolete AEDT-8111-H14 across all specified operating characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both AEDB-9140-H14 and HEDS-5540#H14 are active production parts from Broadcom Limited and provide direct functional substitution for the obsolete AEDT-8111-H14.

AEDB-9140-H14 is the manufacturer-recommended substitute. This part maintains all critical electrical and mechanical specifications. The MSL rating of 3 (168 Hours) indicates standard moisture sensitivity handling requirements for storage and assembly operations. ROHS3 compliance ensures environmental regulatory alignment for new designs and manufacturing processes.

HEDS-5540#H14 offers an alternative substitute with identical electrical specifications. This part features MSL 1 (Unlimited), providing less restrictive moisture sensitivity requirements during storage and handling. ROHS3 compliance is maintained. The orientation specification (Vertical) differs from the main part, which may influence mechanical integration in specific mounting configurations.

Both substitutes carry identical export classification (EAR99) and tariff codes (8543.70.4500), ensuring consistent regulatory and logistics treatment.

Frequently Asked Questions (FAQ)

Q: Can AEDB-9140-H14 and HEDS-5540#H14 be used interchangeably with AEDT-8111-H14?

A: Both parts satisfy all critical electrical and mechanical parameters: 400 PPR optical encoder, quadrature with index output, 5V supply, 5mm open center actuator, and terminal pin termination. Functional substitution is supported across these specifications.

Q: What is the difference in Moisture Sensitivity Level (MSL) between the substitutes?

A: AEDB-9140-H14 carries MSL 3 (168 Hours), requiring controlled moisture exposure during storage and assembly. HEDS-5540#H14 carries MSL 1 (Unlimited), allowing unrestricted moisture exposure. Selection depends on manufacturing environment and storage protocols.

Q: Are both substitutes RoHS compliant?

A: Yes. Both AEDB-9140-H14 and HEDS-5540#H14 are ROHS3 compliant. The original AEDT-8111-H14 RoHS status was not specified in available documentation.

Q: Does the orientation specification affect substitution?

A: HEDS-5540#H14 specifies Vertical orientation, while AEDT-8111-H14 orientation is not specified. Mechanical integration requirements should be evaluated against specific application mounting geometry.

Q: What is the inventory status for these substitutes?

A: AEDB-9140-H14 has 975 pieces in stock. HEDS-5540#H14 has 1530 pieces in stock. Both are available as active production parts from Broadcom Limited.
